Bearing Bracket Alignment for Rear Power Lift Stabilizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bearing arrangements for side stabilizers of rear power lifts in agricultural utility vehicles face inefficiencies in mechanical properties, leading to excessive clamping forces and friction, which complicates assembly and increases costs due to larger dimensions and unnecessary mechanical stress.
Innovation Solution
A bearing arrangement where the clamping force is aligned parallel to the tensile force at the bearing point, allowing for directional flexibility and reduced friction, enabling smaller and more cost-effective clamping devices, and allowing for easier assembly and greater ground clearance by optimizing the mechanical connection between the axle housing and the bearing bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the clamping force is not aligned with the tensile force, then the mechanical connection between axle housing and bearing bracket is stable, but the clamping devices require larger dimensions and greater clamping forces to compensate for directional deviations
Solution Approach 1:
The invention changes the orientation parameter of the clamping force to align it with the tensile force direction at the bearing point. This parameter adjustment optimizes the force transmission efficiency, allowing smaller clamping forces to achieve the same mechanical connection stability.
2Stability of the object's composition
If larger clamping forces are used to ensure stability, then the mechanical connection is more stable, but the clamping devices become larger and more expensive
Solution Approach 1:
By changing the directional parameter of the clamping force to align with the tensile force, the invention achieves optimal force utilization. This eliminates the need for oversized clamping devices, as the aligned configuration maximizes the effectiveness of the applied clamping force.
3Ease of manufacture
If the clamping force is misaligned with the tensile force, then assembly is simpler, but frictional forces increase and mechanical stress is unnecessary high
Solution Approach 1:
The invention optimizes the angular parameter of the clamping force orientation to match the tensile force direction. This parameter optimization minimizes frictional forces and unnecessary mechanical stress, while the alignment actually simplifies the assembly process by providing a clear force transmission path.
4Strength
If the bearing bracket is dimensioned larger to handle misaligned forces, then the mechanical connection is more robust, but the ground clearance is reduced and assembly is more difficult
Solution Approach 1:
By changing the force alignment parameter, the invention achieves robust mechanical connection with properly dimensioned bearing bracket. The aligned force configuration eliminates the need for oversized components, maintaining ground clearance and assembly ease while ensuring structural robustness.

AI summary
The invention relates to an arrangement (10) comprising a bearing bracket (12) and an axle housing (14). The bearing bracket (12) serves to support a side stabilizer (18), which, in its operational installation position, mechanically couples the bearing bracket (12) to a rear power lift (20). The axle housing (14), which has a central longitudinal axis (32), accommodates a rear axle (32) of an agricultural vehicle (16). The bearing bracket (12) has a bearing point (28) for the movable support of the side stabilizer (18) and is connected to the axle housing (14) by a clamping force (F_s). The clamping force (F_s) is aligned parallel to a tensile force (F_z) acting on the bearing point (28) in the operational installation position.
